T=1/p+1/q make q the subject​

Mathematics
1 answer:
Lady bird [3.3K]3 years ago
8 0

Answer:

q = \frac{p}{tp-1}

Step-by-step explanation:

Given

t = \frac{1}{p} + \frac{1}{q}

Multiply through by pq to clear the fractions

tpq = q + p ( subtract q from both sides )

tpq - q = p ← factor out q from each term on the left side

q(tp - 1) = p ← divide both sides by (tp - 1)

q = \frac{p}{tp-1}

A sweater originally priced at $80 was marked down by 25%. What was the sale price of the sweater?
crimeas [40]
The original price of the sweater is $80 which is 100% of the price.
If the price is reduced by 25%, then the new price is 75% of the original price since 100% - 25% = 75%.
Now we need to find 75% of $80.

To find a percent of a number, multiply the percent by the number.
To convert a percent into a decimal, divide the percent by 100 which is the same as moving the decimal point two places to the left.

Here's how to change 75% into a decimal.
75% = 75/100 = 0.75

Here's how you calculate 75% of $80.
75% of $80 =

= 75% * 80

= 0.75 * $80

= $60

Answer: The sale price is $60.
